You're mysql query isnt a valid one, first off, at the end of querys you should get use to doing this:

mysql_query(blah) or die(mysql_error());

That will tell you if the query doesn't work.

Really, without seeing your table there isnt much that I can tell you to fix, just check all your names and do what I said above. Also, it doesn't hurt to echo $query2 to find out what it says inside that, if it's not a valid pointer your sql will fail. Try messing around with what I said a little and if it still doesn''t help, come back.

Oh also, at the top of your put this:

error_reporting ( E_ALL);

That will help in deciding on what the errors specifically are.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-30, 30' at line 1
